High current inductors for HF applications

April 20, 2016 // By Graham Prophet
Coilcraft's SLR Family of high current, shielded power inductors hash current ratings up to 100A and inductance values from 85 to 370 nH, making it suitable for high frequency applications such as multi-phase VRM/VRD/EVRD regulators, Intel IMVP compatible systems, and GPUs/video graphic cards.

The inductors also feature a tight DCR tolerance (±5.4% to ±10%) for lossless, inductor DCR-based current sensing; the SLR Family comprises five product series: the SLR1050, SLR1065, SLR1070, SLR1075 and SLR1190.

The compact SLR1050 Series offers an inductance range of 85 to 220 nH and current ratings up to 86A in a 10.2 x 7.0 x 4.95 mm package. It is offered in three DCR versions for optimal efficiency and accuracy. The SLR1190 offers the highest current ratings in the family – up to 100A – and an inductance range of 150 to 370 nH. It measures 11.2 x 10.3 x 9.0 mm.

All SLR Family inductors feature RoHS compliant, matte tin over nickel over copper terminations and offer a maximum reflow temperature of 260°C.
